Lennon being a Reagan supporter makes sense. Lot’s of boomers changed there views on life and the world as the 70’s ended. A lot had kids, like Lennon, and time to review what their radical views actually accomplished. This story on Lennon liking Reagan is true. We have someone on the scene back in the day give specifics with his anecdotes. What does the writer use to support his argument? Nothing.
You probably already know this, but Lennon wasn’t a boomer, and boomers had already helped reelect Nixon in 1972 with the majority of their vote.
